Embodiment

[0023] Embodiment: a kind of circulation method of cooling water (see Figure 1-3 ), characterized in that it consists of the following steps:

[0024] (1) When the water is within the range from the initial temperature to the set temperature, use the circulation device to circulate the cooling water;

[0025] (2) When the temperature of the circulating cooling water is higher than the set temperature, the artificial refrigeration mode is started;

[0026] (3) When the water temperature returns to the set temperature after artificial refrigeration, continue to use the circulation device to circulate the cooling water.

[0027] The above-mentioned artificial refrigeration method that starts after the temperature of the circulating cooling water is higher than the set temperature can be the way of cooling the circulating water by using semiconductor refrigeration components or draining the circulating water that is higher than the set temperature in the circulating device and the...

Abstract

A cooling water circulation method is composed of the following steps: (1) when the water is within the range from the initial temperature to the set temperature, the cooling water is circulated by a circulation device; (2) when the temperature of the circulating cooling water is higher than the set temperature After the temperature is fixed, the artificial refrigeration mode is started; (3) when the water temperature returns to the set temperature after artificial refrigeration, continue to use the circulation device to circulate the cooling water. Advantages of the present invention: 1. High refrigeration efficiency, which can quickly reduce the temperature of circulating cooling water to meet the needs of experiments; 2. Significant water-saving effect, which can save 20-50 times of cooling water; 3. Semiconductor refrigeration is a Green refrigeration technology avoids the destruction of the atmospheric ozone layer due to the leakage of conventional refrigerants. At the same time, due to the use of circulating cooling water, when replacing the cooling water, it can fully utilize part of the heat capacity of the water from the inlet water temperature to the set temperature instead of Start semi-conductor refrigeration, thus saving both water and electricity; 4. It has broad promotion prospects.

Description

(1) Technical field: [0001] The invention belongs to the technical field of refrigeration, in particular to a cooling water circulation method. (two) background technology: [0002] The problem of water resources is one of the most prominent issues in the sustainable development of my country's social economy in the 21st century, and it is also a major issue of widespread concern in the world. It is facing an increasingly severe situation. How to find out a reasonable, feasible and positively effective solution to the water resources problem from the lack of water resources that has plagued my country's social and economic development for a long time has become an important topic to be studied and solved at present. Because of the limited water resources, it is necessary to use water scientifically and rationally, and all walks of life are exploring various water-saving measures. In industrial production, water-saving technologies such as steam condensation reuse, indirect ...
